New Balance 940v2

Noticeably lower heel to toe drop (the 940 was up around 15mm). Rearfoot feels more stable, not firmer. The N2 cushioning seems to not compress as much as the cushioning in the 940 did. The upper is more comfortable, and the overlays don't rub against the top of my big toes ( I had to skip the first set of eye on the 940 to be comfortable).

The 940v2 is still the latest version, its been out for about a year. (The 940v1 was out for 2 years before it was updated)

I tried the 860v4. Its a decent shoe, but Its stiffer than the 940v2, nd the toe is more pointed, so it didn't fit my wide feet as well. I prefer the 940v2, but you should try them both and see what works best for you
